As the man who literally ended the Targaryen dynasty, an endgame encounter between him and Dany would be pretty awesome.

Along similar lines...well we can speculate about Jon Snow's lineage but we know as a Stark he has no love for the Lannisters either. Jaimie represents all the best and worst of the Lannisters.

I don't know if there's any real payoff in a Brienne-Jaimie "romance," as it seems likely they played a part in each other's development, but it's definitely a thing.

Dany has already linked up with Tyrion, is the farewell from last season really the last time the two brothers will meet?
